I think you're missing the point here Don. It's one thing to see some Octopus species moving from one point of cover to another. But for a benthic species like a Mimic or Wonderpus
to head up into water column goes entirely against the predisposition of such species. Its not that Octopus can't swim up, it just goes against there evolved form and behaviors. The
few occasions I have personally witnessed an octopus free swimming were all due to it feeling under pressure. In all instances the octopus went to ground as soon as it could. Such
instances are extremely rare to be a photo oppurtunity as they happen very quickly and the octopus nearly always are heading rapidly away, escaping.
What is clear, is that competitors in such shootouts are under self made pressure to get wow shots in a short space of time. For some obviously the image comes before the needs
of the subject being photographed. Shame if a website promoting underwater macro photography would actively promote an anything goes attitude. Even worse if it were to then
suppress any discussion to the contrary.
